I had eye surgery and missed 2 weeks of lectures here is an example question of what we are learning Inwas wondering if someone can explain to me how to solve it?

Two constant forces act on an object of mass m = 5.00 kg object moving in the xy plane as shown in the figure below. Force 1 is 25 N at 35.0 degrees , and force 2 is 42.0 N at 150 degrees. At time t = 0, the object is at the origin and has velocity (4.00i + 2.5j) m/s.

A) Express the two forces in unit-vector notation. Use unit-vector notation for your other answers.

B) Find the total force exerted on the object.

C) Find the objects acceleration

D) Now, considering the instant t = 3.00s find the objects velocity

E) position

F) kinetic energy from 1/2mvf^2
